    "abstract": "A semi-analytical method evaluates the error probability of DPSK signals with\nintrachannel four-wave-mixing (IFWM) in a highly dispersive fiber link with\nstrong pulse overlap. Depending on initial pulse width, the mean nonlinear\nphase shift of the system can be from 1 to 2 rad for signal-to-noise ratio\n(SNR) penalty less than 1 dB. An approximated empirical formula, valid for\npenalty less than 2 dB, uses the variance of the differential phase of the\nghost pulses to estimate the penalty.",
